<P>PROBLEM TO BE SOLVED: To provide a hopper for aggregate storage, capable of effectively suppressing and removing arching formation inside the hopper even in a simple and low-cost device configuration, and the arching removal method. <P>SOLUTION: An air blaster 6 for instantaneously jetting compressed air to the inside of a hopper body 2 is disposed at a prescribed position on a sidewall of the hopper body 2, and a pair of partition plates 11 are disposed roughly in parallel along both sides of a compressed air jetting position from a nozzle 9 of the air blaster 6 inside the hopper body 2. Then, when removing arching A formed inside the hopper 1 for the aggregate storage of the configuration, the arching A formed between the pair of partition plates 11 is crashed by the compressed air jetted from the air blaster 6 first, the support force of the arching A formed between the respective partition plates 11 and the inner wall of the hopper body 2 is weakened accompanying the crash, and it is made to follow, crash, and is removed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
